Categories with namespace names (e.g. Category:Wikipedia:foo) - Pywikipedia-l

14 Jun 2011

Hi,

Noticed one of my scripts failing because I tried to instantiate a category
named "Wikipedia:Globalt perspektiv-samtliga" (it's in Swedish Wikipedia,
here's the actual category:
http://sv.wikipedia.org/wiki/Kategori:Wikipedia:Globalt_perspektiv-samtliga)

This fails:
    myCat = pywikibot.Category(mySite, "Wikipedia:Globalt
perspektiv-samtliga");

The error is:
    ValueError: 'Wikipedia:Globalt perspektiv-samtliga' is not in the
category namespace!

Creating it as a page with namespace set to 14 results in:
...
 >> myPage = pywikibot.Page(mySite,
'Wikipedia:Globalt perspektiv-samtliga', ns=14);
...
 >> print myPage.title();    
Wikipedia:Globalt perspektiv-samtliga
...
 >> print myPage.namespace();     4

The title's namespace overrides the given option, which itsn't what I would
expect.  However, if I add the category namespace prefix to the title
(localised to Swedish it's "Kategori:Wikipedia:Globalt
perspektiv-samtliga"), I get the right namespace and such.

Not sure if this is a bug or a feature, so I figured I'd post a note here
and see if anyone had any views on it, rather than just file the bug in SF.

Cheers,
Morten
